BRAIDING-MACHINE Specification of Letters Patent.

Patented July 30, 1907.

A li atio fil d November 28, 1905. Serial No. 289,499.

To all whom it may concern:

Be it -known that I, HE RMANN .I LIUs QUAM- BUSCH, a subject of the Emperor of Germany, residing at Beckacker, near Langerfeld, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Braiding-Machines, of which the following is a specification.

In braiding and lace-making machines the crossed threads are beaten up that it to say, forced up to the thread-collector, located at the place of plaiting or twisting, by a so-called beater. Two groups of heaters have been provided for this purpose, working alternately, in such manner that the one beater-group holds the crossed threads it has beaten up at the thread-collector, while the other group is about to heat up to the collector the crossed threads it has taken up. The beater-groups are actuated in the necessary manner by two eccentric tracks exercising a counter action. The defect of the method is, that the beater-edges which seize the crossed threads strike against the threadcollector with increasing force, the more the limit of the stroke of the heaters deviates from the correct stroke, either owing to inexact adjustment of the parts operating the heaters or to wear and tear. Owing to the heaters continually striking the collector, the beater edges which push the crossed threads before them gradually become blunt, and in time present a bur, which is injurious to the threads, since it causes them to fray and often even cuts them through. The threadcollector itself moreover, becomes grooved owing to the repeated blows of the heaters, and these grooves, especially at the bottom edge of the collector, greatly obstruct regular working. Even the use of hardened steel heaters and a hardened collector does not really obviate the defect, while other disadvantages attend the employment of such hardened parts, which, moreover, involve very considerable extra outlay. Another dis-advantage of the said method of operating the heaters is the intermittent action which is involved by the tracks of the two eccentrics on change of the stroke. For this intermittent action results in a jerky motion of the heaters; and further-more, especially in view of the large number of heaters and the high speed of revolution of the eccentrics, severe shocks are experienced in the machine, whereby proper operation of the mechanism is obstructed and the wear and tear of the parts greatly increased.

With the beater forming the subject of the present invention all these defects are entirely overcome by providing mechanism of such description that the advance of the beater is effected by a spring up to a cer tain limit which is determined by a heater stop, while the retreat of the beater is effected by means of a simple crank-motion, in such manner, that within one revolution, the half of one stroke is utilized for the rearward motion of each beater of the one group, and the half of the other stroke for the rearward motion of each beater of the second group. In this way the heaters, owing to the spring-pressure, are advanced toward the thread-collector, and the extent of their motion limited by the stop which arrests them, in such manner that their end which holds the crossed threads exactly reaches the collector, without, however, striking the latter a hard blow. The reciprocation of the heaters is not intermittent, since in both directions they must follow the always uniform strokes due to the rotation of the crank, in the advance owing to the spring, and in the retreat on account of the half-stroke. This method of operating the heaters also has the advantage of preventing the beater-ends from being jerked aside.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of the new beatingup device. Fig. 2 is a vertical section taken on the line A-B of Fig. l, the eccentric having made a half revolution. Fig. 3 is a fragmentary plan of Fig. 1.

The heaters a of the one group and the heaters 12 of the other group which, as is well known, are disposed alternately in radial position round the plaiting-point and the thread collector c, are carried by supports d, which stand on a stationary plate e, secured to the tubular support f, located at the center of the machine. Each beater slides on a guide g, which is secured to the support d with capability of adjustment in the direction of the beater. This adjustment can, as the drawings show, be effected by the employment of an arm 9 pivoted at the point 9 and secured by means of a bolt 9 passing through a curved slot 9 Or the guide 9 itself may turn ona bolt andbe adjustably mounted in a slot. The corners of the guide 9 are suitably rounded, in order to admit of the unobstructed up and down motion of the free end of the heater. The guide 9 also serves as stop for the beater, the tail of which is bent round so as to grip the guide; the free end of the heater can thus only advance under the influence of the spring 2' until the bent tail of the beater strikes the guide g. 111 view of the adjustahility of the guide, the extent of advance of the beater toward the collector can be determined with the greatest exactitude. In view of the stroke of the beater being a light and easy one, the guide may be made of vulcanite, lignum vitae, or like material.

It h is a bell crank lever with the limb h of which the beater is connected. The beater is pressed toward the collector c by the spring i. In the particular construction shown in the drawing, the spring i presses against a rod 70, connected at the opposite end to the lever-arm h.

011 the central support f the sliding collar Z is provided below the plate e, on which collar there rests the plate m, having apertures m through which pass the rods n, secured to the arms h of the levers h h The plate on is connected, with the aid of rods p, with a crank, or an eccentric 0 having a crank motion, so that on rotation of the eccentric, the plate m works uniformly up and down on the support f. The throw of the eccentric is so selected that half of it is sufficient for the beater-motion; and on the rods 7L, stops it, are provided, which stops, in the case of the rods n for the heaters a of the one group, are located above the plate m, and in the case of the rods of the boaters b of the other group, be low the plate m. Thus on ascent of the plate m, the heaters a are retracted from the collector 0 directly the plate strikes the stops n, of the rods 01.; while on descent of the plate in a like retrogressive motion is imparted to the heaters b, when the plate strikes the steps a, of the rods a lying below it. Since the motion of the heaters of the group a only takes place during the second half of the upward stroke of the plate m, and the motion of the beater group b on the second half of the downward stroke, it is obvious that the heaters of both groups occupy their end positions alternately, so that they are at rest for a certain period also in the position at the collector c. In this manner the crossed threads beaten up by one group are held at the collector, until the heaters from the other group have brought up their crossed threads to the collector.

For the purpose of insuring the free ends of the boaters lateral guidance, they are passed between members q secured to stems or pins q which serve at the same time as holders for. the front part of the beaters, which pass through perforations or holes q In order that the beater-ends, in addition to their forward and back motion, may also move in such manner that at the commencement of their advance-motion they rise to the level of the plaiting-threads r, and on retreat descend below the threads, the pins Q1 of the beater-group a are secured to a vertically reciprocating plate s,.and the pins of the other beater-group b to a plate t, which likewise reciprocates vertically, but independently of the plate 3. In correspondence with the alternation of the forward and backward motion of the beater-groups therefore, there takes place also their up and down motion. These motions are effected by means of cams u and 1), on which rest the rods 21,, '0 which engage the plates t and s respectively by means of forked grippers t .9 Through the vertically reciprocating motion of the plates s and t, due to the rotation of the cams, it is obvious that the beaters, turning correspondingly on the guides g, will be given the necessary motion for bringing them into and out of the plaiting-threads.
